LlSTlNG-PLOW..

SPECIFICATION forming part of Letters Patent No. 755,113, dated March22, 1904.

Application filed April I, 1903. Serial No. 151,102. (No model.)

To all whom it may concern.-

Be it known that I, ENOS P. CURREY, a citizen of the United States,residing at Wellington, in the county of Sumner and State of Kansas,have invented a new and useful Listing- Plow, of which the following isa specification.

This invention relates to plows of that class which are known aslisting-plows and it has for its object to provide a listing-plowcomposed of two separate turning-plows-viz., a right-hand and aleft-hand plow joined together and specially connected by means of aplow-point of special construction.

- The turning-plows used in connection with my present invention aremainly of the pattern shown and described in my application for LettersPatent of the United States, Serial No. 110,874, filed June 9, 1902. Inthe said application for Letters Patent I have shown, described, andclaimed a turning-plow embodying in its construction a landside, amoldboard, a wear-plate, a share, a supporting-- plate, and a point, allsuitably constructed and.

related with regard to each other. By my present invention theindividual plows may be simplified by constructing each of a landsidehaving a supporting-plate, a wear-plate, and

a share or blade of thin hard steel clamped between the supporting-plateand the wearplate, each of said plows being adapted to he used inconnection with a single point or, when the device is to be used as alister, witha double point, which, in conjunction with auxiliaryconnecting means, serves to firmly unite the plows for listing purposes.

With these and other ends in view, all of which tend toward theproduction of a device ofthe class described which shall possesssuperior advantages in point of simplicity, durability, and generalefficiency, my invention consists in the improved construction, ar-

rangement, and combination of parts, which will hereinafter befullydescribed, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of a listing-plowconstructed in accordancev with my invention. Fig. 2 is a bottom planview of the same; Fig. 3 is a perspective view of the point detached.Fig. I is a bottom planview of the point detached,

Fig. 5 is a perspective view of the members composing one of, the plows,except the point, disassembled. Fig. 6 is a transverse sectional viewtaken on the line 6 6 in Fig. 1.

Corresponding parts in the several figures are indicated by similarnumerals of reference. In the accompanying drawings, 1 and 2 designate,respectively, a right and a left hand plow assembled and connected toform a lister. Each of these plows, as will be seen by reference to Fig.5 of the drawings, is composed of a landside 3, having anoutwardly-extending wing 4, which is shaped like a moldboard and whichconstitutes the supporting-plate of the plow.

5 designates the wear-plate, which is supported upon the wing l, andwith which it is connected by means of bolts 6, and 7 designates theshare or blade, which is clamped between the lower edges of thesupporting-plate and the wear-plate. As is the case in my formerapplication for patent, to which reference has already been made, theparts of the plow except the landside are preferably constructed ofsheet-steel, the weight of which is not excessive, but which iseminently well fitted to resist wear and which may be readily bent intoa shape which will present little frictional resistance to the progressof the plow.

It will be observed that the construction of the individual plow ashereinafter described is simpler and contains fewer elements thanthedevice shown and described in my former application for LettersPatent; but I desire it to be understood that I reserve the right toconstruct the individual plow of my present device entirely and strictlyin accordance with the construction set forth in said application andthat, furthermore, I reserve the right to 'vary the construction to anyextent within straps of wrought-iron of suitable dimensions,

to which the supporting-wings & may bewelded or otherwise suitablysecured.

' 8 designates the plow-point, which, consists of a forwardly anddownwardly tapering bar of iron, upon the upper side of which is secureda plate 9, forming laterally-extending wings or flanges 1O 10, and whichis at its lower end double-beveled, so as to form an earth-engaging'point 11 of proper construction. To the under side of the bar 8, at thefront end of the latter, is secured a plate 12, between the upper sideof which and the under sides of the flanges 10 are formed recesses 14,adapted to receive the points of the plows 1 and 2. When the points ofsaid plows are inserted into the recesses 14, it will be seen that thelandsides 3 of the said plows will be spaced apart by the bar 8, withwhich they are connected by means of a transverse bolt 15. Between therear ends of the landsides 3 3 may be inserted a washer-plate orspacing-plate 16, which is also to be retained in position by means of abolt 17 or other suitable connecting means.

It is obvious that handles and a standard are to be provided, which maybe connected with my improved listing-plow in any suitable manner. Isuggest that the lower end of the plow-standard may be secured betweenthe landsides in the position occupied by the washer-plate 16. Suitablebraces will also be provided in order to complete the plow structure.

My improved listing-plow may be used individually, or as a unit ormember of a gangplow or in any other manner that may suggest itself, orthe right and left hand plows of which it is composed may be usedseparately, as will be readily understood.

From the foregoing description, taken in connection with the drawingshereto annexed, the construction and operation of my invention will bereadily understood, as well as the advantages accruing from'saidconstruction. The individual plows constituting my improved lister areextremely simple in construction and capable of being manufactured at avery moderate price. When used separately, separate points may beprovided for them, although the double point herein shown and describedmay be successfully used in connection with either the right-hand orlefthand plow. When the plows are assembled to form a lister, theirlandsides are slightly spaced apart by the intervention of the bar ofthe point, and the flanges and bottom plate of the latter cooperate toform recesses in which the points of the individual plows are seated andprotected. By this I mean that said points being seated in said recessesare protected from dislocation by any obstructions that may beencountered, so that they may out under the soil in a very efiicientmanner. The wings or flanges 10 of the top plate 9 of the point willoverlap the inner edges of the wear-plates, and consequently noobstruction will be offered to the sliding of the dirt from the pointonto the wear-plates and the moldboards above them, whereby it is turnedin an outward direction. It will thus be seen that the said point notonly serves to space the individual plows l and 2 properly apart, butalso serves to assist in connecting the same in such a manner as toinsure perfect rigidity and stability of the parts in operation.

It is to be'understood that moldboards may be attached to the upperedges of the supporting-plates abutting against the wearing-plates andthe upper edges of the point, making a complete joint and a smoothsurface.

I desire it to be understood that while I have in the foregoingdescribed a simple and preferred form of my invention I do not limitmyself in regard to the details thereof, but reserve the right to anychanges, modifications, and alterations within the scope of my inventionand which may be resorted to without departing from the spirit orsacrificing the utility of the same.

Having thus described my invention, I claim 1 1. A listing-plow composedof right and left hand members, a spacing-bar interposed between thelandsides'of said members and provided with sockets to inclose thepoints thereof, and auxiliary connecting means.

2. In a listing-plow, the combination of right and left hand members, aspacing member interposed between the landsides of the same andconstituting a point provided with sockets to inclose the points of saidright and left hand members, and auxiliary spacing and connectlng means.
